yesterday, i saw this bike got a chance to examine few things. it is indeed a classic beauty.This bike is totally comparable with dlx coz if dlx has disc brake then this bike has self start so score level in this regard.but its engine is better than dlx in every aspect so IMHO ybz has lead on dlx.Also checked rims and tyres. As it has spokes wheels and with front 2.75 18 and rear 90/90 18 sized tires so i thought it would had also copied dlx rim at rear like Ravi piaggio but it doesn't copied the deluxe rear rim (2.1 inch wide) and its rim was slightly thin than dlx but indeed bit wider than GS . its size was 1.8 inch and on this rim, 90/90 service cruiser tyre was looking perfect. i think if anyone wants to install a 90/90 tyre on his gs, then this rim would be perfect choice. (niether thin nor very wide) and for 100/90 tyre, dlx rim would serve better.
